Stuart Fitzgerald, Chief Executive Officer, said:

On 1 July, I stepped into my new role as CEO of Subsea7 with a clear vision: to continue executing our strategy in the subsea and renewable energy markets while progressing towards the creation of a strong and prominent global competitor in energy services through our proposed merger with Saipem.

Today, the success of our strategy is evident in another solid set of quarterly results. Underpinned by a combination of a favourable market environment, active risk management and a focus on excellence in project delivery, the Group delivered good margin expansion in the quarter enabling an increase to our Adjusted EBITDA margin guidance for full year 2026. Alongside a high level of project execution activity, we continued to replenish the backlog. Order intake reached $2.1 billion in the second quarter and our high-quality backlog of $13.6 billion provides strong visibility for both this year and next. Longer term, the outlook for the business remains positive. Tendering activity is high, reflecting the attractive economics and strategic importance of the prospects in our target markets. We remain focused on long-term value creation through a combination of operational excellence, effective utilisation of our modern fleet and continued capital discipline.

As we move towards completion of our proposed merger with Saipem, confidence in the opportunity ahead continues to grow. The proposed merger process remains on track. Integration planning is advancing well and continues to highlight the potential for the combined Group to deliver meaningful benefits for clients, strengthen its position as a strong and prominent global competitor in energy services, and create substantial value for shareholders.

Second quarter project review In Subsea and Conventional, activity was high throughout the second quarter, with a vessel utilisation of 85%. In Norway Seven Vega, Seven Arctic, Seven Navica and Seven Oceanic worked on pipelay and umbilical installation at Yggdrasil, Irpa, Fenris, Bestla and Fram Sør. In Brazil, Seven Oceans was active on Búzios 8 and Mero 4, supported by Seven Merlin. Seven Seas transited to the US where it carried out flexible flowline installation at Laser Shark and began umbilical installation at Monument. Finally, Seven Pacific spent the quarter in Côte d'Ivoire working on the Baobab FPSO hookup.

In Renewables, following the seasonal low of the first quarter, vessels returned to work and utilisation was 92%. During the second quarter, Seaway Ventus installed 26 monopiles at East Anglia THREE in the UK, while Seaway Strashnov installed monopiles in France. Cable lay vessels Seaway Aimery and Seaway Phoenix completed class renewals before working on Hornsea 3 and East Anglia THREE in the UK, supported by Seaway Moxie. Seaway Alfa Lift installed transition pieces at Inch Cape in the UK.

Second quarter financial review Revenue was $1.9 billion, growth of 10% when compared with the prior year period. Adjusted EBITDA was $471 million equating to a margin of 24.4%, up from 20.5% in Q2 2025.

Depreciation and amortisation fell to $154 million, from $175 million in the prior year period and $174 million in the first quarter of 2026, as a result of a reduction in the chartered fleet. After other gains and losses of $46 million, primarily driven by foreign exchange gains, net finance costs of $5 million and taxation of $104 million, net income was $254 million.

Net cash generated from operating activities in the second quarter was $570 million, including a $139 million favourable movement in net working capital. Net cash used in investing activities was $70 million mainly related to purchases of property, plant and equipment. Net cash used in financing activities was $528 million including dividend payments of $414 million and lease payments of $52 million. The Group entered into foreign exchange forward contracts to mitigate the foreign currency exposure of the dividend. The net cash impact of the dividend to the Group, after including the gain on foreign exchange forward contracts, was $403 million. During the quarter, cash and cash equivalents decreased by $28 million to $1,046 million and, at 30 June 2026, net cash was $190 million, including lease liabilities of $363 million.

Second quarter order intake was $2.1 billion comprising new awards of $1.8 billion and escalations of $0.3 billion resulting in a book-to-bill ratio of 1.1 times. Backlog at the end of June was $13.6 billion, of which $3.9 billion is expected to be executed in the remainder of 2026, $5.6 billion in 2027 and $4.1 billion in 2028 and beyond.

Guidance

Adjusted EBITDA margin is expected to be approximately 24% (from 23% previously) while we continue to anticipate revenue in the range between $7.4 and $7.8 billion.
